The pads they put on at the factory are generally not the same pads you get at the dealer. I had several Tacoma pads I had to source from the dealer for a short while many years ago. The OEM pads lasted 35k-40k miles. The OES pads I bought from the dealer were no better in terms of performance or life than subsequent after market pads.
OEM parts are designed to exceed the warranty period. Anything after that is icing on the cake.
